Goal

You will learn how to interact with iRODS via WebDAV. You will:

  • Connect to the iRODS WebDAV interface via Web browser
  • Connect to the iRODS WebDAV interface through a WebDAV client
  • Upload and download data and collections

1. Connect to the iRODS WebDAV interface via Web browser

1.1 Set up

Just copy the url of the test iRODS environment in your web browser: https://rsc-test1.irods.surfsara.nl/
You should see a pop-up window, which asks your iRODS username and password. Enter them.
You should now see the content of your iRODS home folder.

2. Connect to the iRODS WebDAV interface through a WebDAV client

2.1 Set up

Perform the following steps:

git clone https://github.com/ccacciari/iRODS-RDM-HPC-course.git
cd iRODS-RDM-HPC-course

We will use a client called rclone (https://rclone.org). It is already available on Lisa.
This client supports many different protocols and interfaces, included WebDAV.

cd iRODS-RDM-HPC-course
rclone ls :webdav: --webdav-url=https://rsc-test1.irods.surfsara.nl --webdav-vendor=other --webdav-user=irods-user1 --webdav-pass=xxxxxxx

Does it work? The rclone client requires an "obscurated" password:

rclone obscure mypassword
rclone ls :webdav: --webdav-url=https://rsc-test1.irods.surfsara.nl --webdav-vendor=other --webdav-user=irods-user1 --webdav-pass=myobscurepassword

3. Upload and download data object and collections

Now if you want to upload a file:

rclone move alice.txt :webdav: --webdav-url=https://rsc-test1.irods.surfsara.nl --webdav-vendor=other --webdav-user=irods-user1 --webdav-pass=myobscurepassword
rclone ls :webdav: --webdav-url=https://rsc-test1.irods.surfsara.nl --webdav-vendor=other --webdav-user=irods-user1 --webdav-pass=myobscurepassword

If you try to reach the webdav interface with your web browser now, you should see the same file.
You can download it with your browser on your pc.
Or download it to Lisa via rclone:

rclone move :webdav:alice.txt alice.txt --webdav-url=https://rsc-test1.irods.surfsara.nl --webdav-vendor=other --webdav-user=irods-user1 --webdav-pass=myobscurepassword
ls -l

You can also try the command copy and delete.
